----------------------+-----------------------
 Here is an update for watch to version 3.3.6. I switched the upstream
 source to procps-ng, as the original project appears to be dead.
 Additionally, I had to apply some patches to get it to build on Mac OS X.

 The main advantage of the new version is the correct handling of color
 escape sequences with `-c`.
